WestLand Resources, Inc. (WestLand) was retained by Rosemont Copper Company (Rosemont) to prepare a series of technical memorandums to supplement the Biological Assessment for the Rosemont Copper Project (Project). This memorandum summarizes proposed Clean Water Act (CWA) Section 404 mitigation measures described in the Rosemont Habitat Mitigation and Monitoring Plan (HMMP) that would benefit special status species listed under the Endangered Species Act (ESA).
